Abstract

The utility model discloses an angle folding ruler and belongs to stationary. The angle folding ruler mainly solves the problem that a protractor is not convenient enough when people use the protractor to draw angles. The angle folding ruler comprises two flat rulers, wherein a complete protractor scale is marked on one end of one flat ruler, length scales are marked on other parts, the other flat ruler is only marked with length marks, the two flat rulers are riveted together through a rivet after the two flat rulers are folded together, and the rivet is arranged on a datum mark of the scale of the protractor. When in use, any flat ruler can be used to measure length, when angles need drawing, the flat ruler without the scale of the protractor can be rotated around the rivet, one side of the ruler is aligned with the angle which needs drawing for confirming two sides of the angle, and thereby the demanded angle can be drawn conveniently and rapidly. The angle folding ruler not only has convenient use, but also can reduce the occupied space and can be easily stored through combining the flat rulers and the protractor.

Description

The angle folding rule
Technical field
The utility model relates to a kind of stationery, particularly a kind of angle folding rule.
Background technology
When the student draws the angle all from not ruler and protractor, and ruler that we had bought at ordinary times and protractor all are independent one, not only lose easily, and be placed in the writing case and take up room very much, be not easy to deposit, draw two points with protractor earlier when drawing the angle, with draw two limits at angle of ruler, it is convenient inadequately to use again.
The utility model content
The purpose of this utility model is to provide a kind of angle folding rule, and it combines ruler and protractor, not only can measure length but also the angle of the required angle of can drawing easily.
The technical scheme in the invention for solving the technical problem is: a kind of angle folding rule, it is characterized in that, constitute by two rulers, one end of a ruler indicates a complete protractor scale, remainder indicates the length scale, another only indicates the length scale above ruler, two rulers are superimposed the back by rivet together, and described rivet is located at the datum of protractor scale.
The beneficial effects of the utility model are: ruler and protractor are organically combined the required angle of can conveniently drawing.Not only easy to use, and reduced and take up room, be easy to deposit.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 protractor scale, 2 rivets.
The specific embodiment
As shown in Figure 1.
A kind of angle folding rule, constitute by two rulers, one end of a ruler indicates a complete protractor scale 1, remainder indicates the length scale, another only indicates the length scale above ruler, be riveted together by rivet 2 after two rulers are superimposed, described rivet 2 is located at the datum of protractor scale 1.
During use, any one ruler can both be measured length, and when needs picture angle, allowing does not have the ruler of protractor scale 1 around rivet 2 rotations, makes one bar limit aim at the angle that will draw, just can determine two limits at angle, thereby conveniently draw required angle.Ruler and protractor are organically combined, not only easy to use, and reduced and take up room, be easy to deposit.
